Requirements for x-ray machine users at OSU are summarized below. These requirements are compiled from the relevant regulations found in Section VII of the OSU Radiation Safety Manual, and the following Oregon Administrative Rules:
- Division 108 - Analytical X-ray equipment (x-ray diffraction machines)
- Division 122 - Industrial X-ray machines (cabinet x-ray machines)
- Division 106 - X-rays in the healing arts (vet med, bone densitometer, medical screening)
Other requirements specific to your program can be found in the Conditions section of your Radiation Use Authorization (posted in the lab with the machine).
Radiation Use Authorization
A Radiation Use Authorization (RUA) issued by the OSU Radiation Safety Committee is required for possession and/or use of any x-ray machine. RUA application instructions (pdf format) can be found here (click here for an MS-Word version).
Each radiation machine shall be registered with the State Health Division before being put into use. Registration will be arranged by Radiation Safety. The Program Director will be responsible for the registration fee charged by the State.
Each machine must be listed on the Program Director's Radiation Use Authorization.
Purchase and Disposal of X-ray Machines
Radiation Safety must be notified before purchase of an x-ray machine.
Due to the potential hazards, liability and registration requirements, X-ray machines may not be sold at open auction through Surplus Property. Machines may only be sold or transferred to recipients eligible to register the machine. Contact Radiation Safety (541-737-2227) for specific instructions.
Most x-ray machines used in research labs are classified as either analytical (diffraction) or cabinet machines.
Training is completed in two parts:
- Radiation Safety Orientation for Analytical and Cabinet X-ray Machines - this is a 1hr training course, scheduled as needed by Dan Harlan. A Prior Dose/Orientation Acknowledgment form is completed and submitted at the end of the session.
- Machine Specific Training, conducted by the Program Director or lab contact. Upon completion of the machine-specific training, the Program Director or Lab Contact completes the Operational Training Acknowledgment Form RSC-108C. Return the form to Radiation Safety.
- Pre-class reading material (pdf)
Dosimeters for Analytical and Cabinet x-ray machine operators
Body badge and/or finger rings are required for analytical (diffraction and flourescence) x-ray operators.
Body badges are required for all cabinet x-ray operators.
Training requirements for X-ray radiography (additional requirements for fluoroscope and CT listed below)
All individuals who intend to use an X-ray machine for veterinary diagnostic purposes must submit form RSC-108G, Veterinary X-ray Operator Radiation Safety Training Acknowledgment. In addition, they must receive individual training and complete the Veterinary X-ray Machine Operational Training Acknowledgment form for each machine they will be using; this training is provided by Vet Med Radiology.
Additional Requirements for X-ray radiography
- Veterinary students participating in their regular course of study may operate x-ray machines under the supervision of an approved operator; the RSC-108G form is not required.
- Licensed veterinarians are not required to provide any documentation of their x-ray training. Forms RSC-108G for prior dose information and machine training form is still reqjuired.
- Veterinary Technicianss are required to attach documentation (certificate or transcripts) to the RSC-108G to indicate completion of 20 hours of approved training in x-ray use and safety.
Additional Requirements for X-ray fluoroscopy and CT
- All fluoroscope use must be reviewed and approved by the radiologist. A DVM may do fluoroscope work if they are credentialed. A copy of the fluoroscope credentials must be on file with Radiation Safety. Contact the Program Director (Radiologist) for fluoroscope credentialing. There are limited options for fluoro credentialing in the State of Oregon. Currently the only option available at OSU is to purchase the credentialing program through R.M. Partnership.
- A Veterinary Radiologist is authorized for X-ray, CT, and fluoroscope work.
- A Radiologic Technologist (RT) is authorized for X-ray and fluoroscope work. For CT work, a copy of the CT credentials must be on file in Radiation Safety.
Dosimetry requirements for Veterinary Medicine
Dosimeters are required for all Veterinary Medicine x-ray machine operators. The Vet Med dosimeter program is managed through Vet Med Radiology.
At least one body badge is required to be worn outside any protective clothing. If a protective apron is worn, the badge should be worn at the collar. If a second badge is issued, it should be worn under the apron on the trunk, between the waist and collar. (OAR 333-106-0050)
Finger rings should be worn under protective gloves.
Licensing requirements for X-ray radiography (does not include fluoroscope and CT)
All individuals who intend to use an X-ray machine for human use diagnostic or research purposes must possess a current license as a Radiologic Technologist or a Limited Permit from the State of Oregon Board of Radiologic Technology or be a student in the Limited Permit instructional program in the Bone Research Laboratory. Copy of the RT license or Limited Permit must be submitted to Radiation Safety.
Additional Requirements for X-ray fluoroscopy
A medical practitioner may do fluoroscope work if they are credentialed. A copy of the fluoroscope credentials must be on file with Radiation Safety. Contact the Program Director (Radiologist) or Radiation Safety for fluoroscope credentialing. There are limited options for fluoro credentialing in the State of Oregon. Currently the only option available at OSU is to purchase the credentialing program through R.M. Partnership.
Dosimetry requirements for Human Use
Body dosimeters (badges) are required for all human use x-ray machine operators. The body badge is required to be worn outside any protective clothing.
